The rate at which an object moves. The average speed v of an object may be calculated by dividing the distance s it has traveled by the time t taken to do so, and may be expressed as:
v = s/t
The usual units of speed are meters per second or kilometers per hour.
Speed is a scalar quantity in which direction of motion is unimportant (unlike the vector quantity velocity, in which both magnitude and direction must be taken into consideration). See also distance-time graph and speed-time graph.
